" CLAMPING DEVICE No. 858L899.-

To all whom it may concern: I

Be it known that I, WILLIAM H'. MoNU'r'r, a citizen of the United States, residing in New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Clamping Devices .for Receptacles, of which the following is a I specification. I a

This invention relates to a formof clamping device arranged to be secured at the of an opening in a plate, where access is to be had at one side of the plate only; such for instance, as an aperture formed in a closed vessel, like a can.

The purpose of the invention provide such a device whereby one serted through an part of a clamping device can beinopening in a plate, and can then be inner side, in conjunction with a second member that co-operates with the other member-and engages the of the opening on the outer side, the members being organized to lock together, and thereby form a. means for attachment of certain devices to the vessel or device of which the plate forms a part. The invention is especially designed for use with cans or vessels for containing inflammable or explosive fl uids such as gasolene, kerosene or the like, whereby a safety device can be secured to the vessel at such point, especially for filling purposes. I 4 I I I i In the accompanying drawings showing an embodimcnt of the present invention, Figure I is a side elevation of the device in position on a plate. I Fig. 2 shows the same in longitudinal section. Fig. 3 is a perspective view of the principal clamping member 'inits flexed or opened position for insertion through an aperture in a plate, the broken lines indicating the aperture. Fig. 4 represents the same inside elevation, and Fig. 5 is a similar side elevation froma different point of view, the circle indicating the aperture through which the member can be inserted. Fig. 6 is a similar view in plan, the broken line indicating the diameter of the aperture through which the member can be inserted.- Fig. 7 represents the same member in side elevation in its normal annular position; and Fig. 8 is a perspective view of the clamping ring for locking the perforated tube to the clamping member. The principal member of the clamping device denoted generally by a is shown as composed of a sleeve portion 12 provided with a flange portion 13 at one end.

This memberq is bisected axially forming two comple- -mental portions that are secured together to swing on an axis perpendicular to the axis of the member and which TO THE NON-EXPLOSIVE SAFETY N. Y., A CORPORATION IOF sourn FOR RECEPTACLES.

Patented July 2, 1:907.

In the construction shown, the two complemental on the flange members in a-linementI 19 may be used at the pivot portions to yieldably' retain the device in. the annular position as shown in Fig. 7. The sleeve member 12 is threaded to engage a clamping member, and is shown as externally threaded, .to engage the internal threads of a clamping nut '20.

Inorder to secure the two members to be secured at the margins of an opening as for instance an apertur 21 in'a plate 22, that is of sufilcient size to permit insertion of the sleeve portion 12 through the aperture, to

Springs 18 and aperture; the clamping member a is pivot to the position indicated in Figs. 3 to 6, in which it will assume a substantially crescent form. The member .can now bepassed through the openin'gas in Figs'. 3 and 5, the aggregate length and "height'iof the two aliniug sleeve portions than the dimension ofjthe into the opening therethrough by giving it a curved movement, that will tend to keep the diameter of the openingin substantial alineme'nt with the diameter of the clamping member. may be attached to the member so that when passed into the opening, it will not be dropped. As soon as the member passes being released the springs will return it to its normal annular position, and it can now be brought to the openiug by the string and grasped by the fingers to draw the sleeve portion through the opening causing the flange the inner side, this position, the nut member 20 can be screwed onto the sleeve, until the margins of-the plate 22 can be clamped between the nut and the flange of the two part member, which can be securely locked in this position. i This means'now clamped inth'e aperture in the plate can be used for any desired purpose. In the device illustrated, a safety tube is shown as secured in the clamping device. A tube 30 having minute preferably provided with small perforations 31, has one end flanged at 32 to engage the upper end of the clamping member a after the tube has been inserted through the .bore in the member as shown in Figs. 1 and 2. is closed by a cap 33, that may also be perforated if desired. A ring nut 34 screws'in the bore of the nut access to the vessel of which top is closed exceptthrough the plate 22'may form the ube, and this will act as a the. perforations of the II safety device preventing cause the fiange portion 13 to engage the margin of the swung on its in this position being less opening, it can' be passed- If desired, a wire or string:

throughthe opening in the plate, upon.

I The lower end of the tube' 5 portions 14 and 15 of the member are pivoted together by pins 16 and 17 passing through suitable ears formed to engage the margin of the opening in the plate from as indicated in Fig. 2. While held in 5 20 and is screwed down on top of the flange 32 of the tube. By this means, the

flame passing into the vessel to cause an explosion. If desired suitable plug member as 36 may screw into the top of the nut member 20 'to close the opening therein.

With the use of this device, a filler tube, or a closing cap, or other device can be attached to a comparatively thin plate forming the part of a closed vessel, or part of a member where access is to be had from one side only. It is only necessary to cut the hole or aperture in the plate, and no threaded portion is needed or any special clamping means such as solder or rivets. It is only necessary to bend up the pivoted clamping member, insert it through the opening, and then bring its sleeve back through the opening and secure the lock nut onto the sleeve from the outside when the device is securely assembled in position. The filler tube is then inserted and its ring nut locks it securely in position. l
